ON/OFF TIME SETTING INSTRUCTIONS
FOR LOADS USING NORMALLY OPEN (NO) RELAY CONTACTS
To set the ON DELAY time:
1. Set dial to the desired length of time that is required to elapse before the load (fan, light, etc.) is to be turned ON. The dial can be set to various positions
within three different time ranges: 5-50 seconds, 1-50 minutes, and 1-3 hours. The dial can also be set to continuous ON and continuous OFF positions.
2. The timer will begin timing the desired interval after the dial is set and the external trigger (by others) connected to START terminal is closed.
3. The red OFF LED will blink at a 1 Hz rate when the load circuit is OFF and is timing the delay. The green ON LED will illuminate steadily when the load circuit
is ON.
4. The timing interval can be restarted from an ON position by opening and reclosing the external trigger.
To set for CONTINOUS ON:
Set dial and align the pointer to the ON position (approximately 12:00 o’clock position). The timer ignores any external trigger signals in this mode. The
green ON LED will illuminate steadily when the timer is set for a continuous ON condition.
To set for CONTINOUS OFF:
Set dial to and align the pointer to the OFF position. The timer ignores any external trigger signals in this mode. The red OFF LED will illuminate steadily when the timer is
set for a continuous OFF condition.
FOR LOADS USING NORMALLY CLOSED (NC) RELAY CONTACT:
The normally closed relay contact is provided to enable a secondary load to be switched at opposite time intervals of the main load (the load controlled by the
normally open contact.) When the load that is connected to the normally open relay contact is ON, the load connected to the normally closed contact is OFF.
When the load that is connected to the normally open relay contact is OFF, the load that is connected to the normally closed contact is ON.
PROGRAMMING & OPERATING THE TIMER
OPERATING PARAMETERS
• The control relay will be energized continuously if the time interval dial is turned to ON. The control relay will be de-energized continuously if the time interval
dial is turned to OFF.
• The control will repeat cycle within 1% of timing range.
• The control will automatically reset after a 1 second power interruption and remain OFF with the red OFF LED illuminated steadily until the external contacts
connected to the START terminal are closed.
• If the external trigger is removed from the timer, it will immediately reset to an “output disabled” condition, thus removing power from the load. It will then
wait for the next timing cycle to commence with an external trigger closure.
• If the time interval dial is moved from one position to another during the active timing cycle, no change will result in the timing or output status for that cycle.
